Contrast delivery developer Acist Medical Systems and HealthTrust, a healthcare group purchasing organization, have entered into a three-year contract for the company's cardiovascular injection technology.

The agreement gives HealthTrust members including hospitals, clinicians and other staff access to the Acist CVi contrast injection system, according to the Eden Prairie, Minn.-based company. The CVi variable flow-rate injection system provides a method of contrast injection during cardiac and vascular angiography procedures that alleviates the use of stopcocks, syringes and tubing.

According to Acist, the three-year contract became effective Dec. 1, 2009.
